JSON+

Serialization of common data types (which are out of the JSON specs) that works out of the box (batteries included).

So far, modules (packages) for Python, Flask and Django are implemented, and they support (de-)serialization of types like:

• tuple and namedtuple
• set and frozenset
• complex, Decimal, and Fraction
• datetime, date, time, and timedelta
• UUID, moneyed.Money, moneyed.Currency

(in addition to basic JSON supported-types like integers, floats, lists, and dictionaries).

Also, encoder and decoder for custom (user) types can easily be registered (see python example).
